I've often thought the same (and then stepped back and wondered if
blast/fasta/hmmer output could be expressed in BNF [ Backus-Naur Form ]).
It seems like an excellent project for an undergrad CS major who wanted to
crossover into bioinformatics. There's too much grunt work involved for
any of us to want to do it, though ;) Maybe we should take this off-list
Jason, but do you have any comments on Parse::ResDecent vs. Parse::Yapp
utility?
